Hi,

I am new to Ansible an trying to achieve this below. Is this possible to set a dictionary property using key in Ansible.

`vars: mydict: keyA: path: ‘path of device A’ error_files: [] keyB: path: ‘path of device B’ error_files: []`

`

- name: collect errors of device A  
set\_fact:  
mydict[‘keyA’].error\_files: “mydict[‘keyA’].error\_files + item ”  
loop: “{{error\_files\_ofdeviceA }}”  
`

Thanks

On the same not, can I use something like below -

`

- name: setting up item property  
set\_fact:  
item.founderror: true  
loop: “{{ device\_list }}”  
`

here device\_list is a list of object where I would like to add/update a property founderror.

Thanks
